Error in copy activity with Oracel 2.0

I am trying to migrate our copy activities to Oracle connector version 2.0. The destination is parquet in Azure Storage account which works with Oracle 1.0 connecter.

Just switching to 2.0 on the linked service and adjusting the connection string (server) is straight forward and a "test connection" is successful. But in a pipeline with a copy activity using the linked service I get the following error message on some tables.

ErrorCode=ParquetJavaInvocationException,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=An error occurred when invoking java, message: java.lang.ArrayIndexOutOfBoundsException:255
total entry:1
com.microsoft.datatransfer.bridge.parquet.ParquetWriterBuilderBridge.addDecimalColumn(ParquetWriterBuilderBridge.java:107)
.,Source=Microsoft.DataTransfer.Richfile.ParquetTransferPlugin,''Type=Microsoft.DataTransfer.Richfile.JniExt.JavaBridgeException,Message=,Source=Microsoft.DataTransfer.Richfile.HiveOrcBridge,'

As the error suggests in is unable to convert a decimal value from Oracle to Parquet. To me it looks like a bug in the new connector. Has anybody seen this before and have found a solution? The 1.0 connector is apparently being deprecated in the coming weeks.

Here is the code for the copy activity:
